Revise review panel for tailings plans
HB 699 revises the laws concerning the independent review panel responsible for evaluating metal mine tailings impoundment plans. The bill modifies the panel's membership requirements, qualifications, and duties, directly affecting metal mine operators and the experts involved in reviewing tailings storage facility designs. Key changes include broadening the qualifications for panel members to allow recognized subject matter experts who are not licensed engineers to serve, in addition to licensed professional engineers. It also mandates that the review panel provide a written report and grants new rulemaking authority to implement these changes.
